When evaluating cloud storage providers, it is dangerous to assume such services are only storage and therefore uncomplicated or that requirements for storage are obvious and therefor inherently met by the service provider.

Never purchase a service without proper vetting; uninformed decisions risk loss of time, money, and even assets. These nine assessment criteria will help you get started in asking the right questions and making a practical, informed decision on using cloud storage for archival or preservation needs.
